I suggest to try tying the enable to ground so as to ensure that there is no interference or unknown phenomenon along the enable which would cause the HV to stop.
The HV will have to be connected to system ground to complete the circuit. My thought is that by connecting the ground on the output side of the power supply as close to the HV input as possible, this will provide a return path of least resistance and keep switching noise along the HV current path from trying to propagate through signal lines.
